I'm still working on the new animation, it's like 50% complete, as you know, Newgrounds, when you try to put a new animation, the title, must be 25 words or less, so when I finish the animation, I will call the animation: Goku & Vegeta vs Kid Buu 2 or something like that, ok?
This fight between these three guys, will be separated in three or four parts, Kid Buu is a really powerful oponent, so Goku & Vegeta won't beat him easily, but I'm sure of this: At the end of the part two, Goku will go Super Saiyan 3, then in the part three, Goku SSJ3 will fight Kid Buu, Vegeta will be damaged, so he won't fight, and then, when Goku is charging a Kame Hame Ha, he will go back to his normal stage, because his Super Saiyan 3 needs a lot of power, so at the end of part three, Goku & Vegeta will fuse and they will create Vegito, part four, even if the fight will be between Vegito and Kid Buu, the title will be called Goku & Vegeta vs Kid Buu 4, because if I put: Vegito vs. Kid Buu, you'll understand that is another fight, not part four of the last fights.
Stay there, soon you will see my work!
